Award Description: Conflict between the sexes over control of fertilization is expected to be widespread among organisms, but its evolutionary consequences are still poorly understood particularly in vertebrate animals. Waterfowl have complex breeding systems that include female partner preferences based on elaborate male plumage and courtship display, and unsolicited reproductive attempts by males other than the female's chosen partner. Female ducks show resistance behaviors and anatomies that have coevolved with male coercion. Ducks are ideally suited to study the evolution of sexual conflict and the evolution of reproductive structures. The project examines how reproductive morphology covaries with season, age, and social environment in a diverse sample of duck species that differ in ecology, territoriality and breeding system. Preliminary results of the project, suggest that male competition plays an important role in the evolution of waterfowl reproductive morphology, that male reproductive morphology is plastic depending on age . . .
